Raised nails or screws should be reset or replaced as they can be a trip hazard or can contribute to an unstable structure. They are normally a sign of excessive expansion and contraction in the timber and can be accompanied by warped or cracked boards. Damaged decking boards and fixings are potential hazards that can lead to structural damage if the cause of the problem is not rectified.

Areas of concentrated fungal growth are of concern as they indicate the presence of excessive moisture and the likelihood of rot. Wet rot makes timber soft and spongy while dry rot causes it to shrink and become highly brittle. Replacing a rotting board is fairly straight forward and should be done before the rot spreads to adjoining boards or structural timbers.

Excessive moisture and rot are also known to increase the risk of borers and termites. Insect infestation in its early stages can be hard to spot but ultimately results in the destruction of timber structures. A pest control specialist should be contacted if you have any concerns of infestation to determine the best overall treatment for your home.
